A canon of mass 1100kg fires a cannonball of mass 6.2kg at a speed of 190ms-1.
a) Calculate the initial recoil speed of the cannon.
b)The purpose of the firing the canon is to transfer chemical energy of the explosive into kinetic energy of the cannon ball, but the cannon is also given kinetic energy. Calculate the percentage of the total kinetic energy that is carried by the cannon ball.
plz help I'm sure you'll agree that this question is confusing
